FLASHING;

To all whom it may concern Be it known that I, HOMER H. DUNLAP, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Flashings; and I do declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention is an improved flashing for use across the angles between roofs and fire walls of chimneys, or for application in other points where flashings are commonly used ormay be used to advantage.

The object of the invention is to prov de an inexpensive flashing which may be easily applied, yet one which will be h ghly elficient 'and durable and will effectively exclude moisture and wind at all times, provision being made whereby the flashing may readily expand and contract-with the parts to which it is secured, under changes in temperature.

With this general object in view, the 111- vention resides in certain novel features of construction and in unique arrangements of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanymg drawing which constitutes a part of this application and in which:

Figure 1 is a sectional perspective of a portion of a roof and fire wall showing the application of the invention thereto, and, Fig. 2 is a true vertical section of the parts shown in Fig. 1.

In these drawings, the numeral 1 designates a roof, while 2 refers to a fire wall rising beyond the edge of saidroof, it being across the, angle between these parts that the improved flashing 3 is applied, the roof proper being covered with any preferred roofing material 4.

The improved flashing 3 is formed by extending one or more intersticed sheets of material such as that shown at 5 across the angle between the wall 2 and roof 1, and by applying a covering 6 of non-drying weather-proof cement to the upper surface Specification of Letters Patent.

non-drying oils, asphalt, pitch or varnish,

and asbestos fiber. It will be understood, however, that I do not wish to be limited to these specific ingredients since as above stated any appropriate cement may be used. The material 5 will be preferably secured along its lower edge to the roof 1 by nails or staples 7, while the upper edge of such material will usually be received in a horizontal groove 8 formed in the wall 2. Here 7 again, however, I do not wish to be limited to this exact manner of anchoring the part in question. Regardless of the manner in which it is anchored, however, the covering 6 will extend beyond its edges onto the wall and roof to which said covering is adhered by its viscous qualities. If the groove 8 be provided, a suflicient quantity of the covering 6 will be worked into said groove to effectively exclude moisture therefrom as will be readily understood.

By constructing the improved flashing in the manner shown and described, it will be obvious that it will be inexpensive yet efficient and durable.

It will be understood that non-drying cement is essential, since it allows readily for expansion and contraction of the flashing with the roof and wall, as the latter parts vary in temperature.

I have shown and described the flashing 3 as applied across the angle between a roof and a fire-wall, but I wish it understood being of such rigidity as to maintain said In testimony whereof I have hereunto set edge in said groove, and a plastic layer my hand in presence of two subscribing Worked into said fabric and closing the Witnesses. groove, said layer ftapering ofi above the V groove and also tapering out over'the roof Witnesses: and beyond the edge of the strip secured H.
